Silverlight 切断文本/将其换行并且无法正确显示

请帮助我理解这背后的问题并解决它，我在获得我想要的文本显示行为方面遇到了很多麻烦。

对于一定长度的字符串，TextBlock 会环绕，但不会更新控件以显示第二行，实际上使部分文本消失。

这在 XamlPad 中运行良好，但在 Silverlight 3 和 Expression Blend 3 中不起作用

<Grid x:Name="LayoutRoot" Background="{x:Null}">
    <Grid.RowDefinitions>
        <RowDefinition Height="Auto"/>
        <RowDefinition Height="Auto"/>
    </Grid.RowDefinitions>
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="Auto"/>
        <ColumnDefinition Width="Auto"/>
    </Grid.ColumnDefinitions>
<Border CornerRadius="20,20,20,20" Grid.ColumnSpan="2" Grid.RowSpan="2" BorderBrush="#FF000000" BorderThickness="1,1,1,1">
    <Border.Background>
        <LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0">
            <GradientStop Color="#FF2100FF"/>
            <GradientStop Color="#FFFFFFFF" Offset="1"/>
        </LinearGradientBrush>
    </Border.Background>
</Border>

<TextBlock x:Name="eventName" Grid.Column="1" Text="Amazing Music" FontSize="24" Margin="5,5,10,5" HorizontalAlignment="Left" VerticalAlignment="Top" Padding="0,0,0,0"/>
<TextBlock x:Name="eventDescription" Grid.Column="1" Grid.Row="1" Text="Amazin music in that house" TextWrapping="Wrap" FontSize="14" Margin="5" HorizontalAlignment="Left" VerticalAlignment="Top" MaxWidth="300" />
</Grid>

Please help me understand the issue behind this and it's fix, I'm having agood deal of trouble getting the behaviour I want with text display.

With certain lengths of strings the TextBlock wraps around, but does not update the control to show the second line, in effect making part of the text dissappear.

This works fine in XamlPad, but not in Silverlight 3 and Expression blend 3

<Grid x:Name="LayoutRoot" Background="{x:Null}">
    <Grid.RowDefinitions>
        <RowDefinition Height="Auto"/>
        <RowDefinition Height="Auto"/>
    </Grid.RowDefinitions>
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="Auto"/>
        <ColumnDefinition Width="Auto"/>
    </Grid.ColumnDefinitions>
<Border CornerRadius="20,20,20,20" Grid.ColumnSpan="2" Grid.RowSpan="2" BorderBrush="#FF000000" BorderThickness="1,1,1,1">
    <Border.Background>
        <LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0">
            <GradientStop Color="#FF2100FF"/>
            <GradientStop Color="#FFFFFFFF" Offset="1"/>
        </LinearGradientBrush>
    </Border.Background>
</Border>

<TextBlock x:Name="eventName" Grid.Column="1" Text="Amazing Music" FontSize="24" Margin="5,5,10,5" HorizontalAlignment="Left" VerticalAlignment="Top" Padding="0,0,0,0"/>
<TextBlock x:Name="eventDescription" Grid.Column="1" Grid.Row="1" Text="Amazin music in that house" TextWrapping="Wrap" FontSize="14" Margin="5" HorizontalAlignment="Left" VerticalAlignment="Top" MaxWidth="300" />
</Grid>

我认为布劳略说对了。通过将文本包装在边框中的堆栈面板中，我能够正确地包装和调整大小。将此 XAML 拖放到未设置宽度和高度的全新用户控件上。

<Border CornerRadius="20,20,20,20" BorderBrush="#FF000000" BorderThickness="1,1,1,1" 
    Height="Auto" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Width="192"
    Padding="5">
    <Border.Background>
        <LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0">
            <GradientStop Color="#FF2100FF"/>
            <GradientStop Color="#FFFFFFFF" Offset="1"/>
        </LinearGradientBrush>
    </Border.Background>
    <StackPanel>
        <TextBlock x:Name="eventName" Text="Amazing Music" FontSize="24" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Padding="0,0,0,0"/>
        <TextBlock x:Name="eventDescription" Text="Amazin music in that house" TextWrapping="Wrap" FontSize="14" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" MaxWidth="300" />
    </StackPanel>
</Border>

I think Braulio's onto something. I was able to get it to wrap and size correctly by wrapping the text in a stackpanel in a border. Drop this XAML onto a brand-new user control that does not have a width and height set.

<Border CornerRadius="20,20,20,20" BorderBrush="#FF000000" BorderThickness="1,1,1,1" 
    Height="Auto" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Width="192"
    Padding="5">
    <Border.Background>
        <LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0">
            <GradientStop Color="#FF2100FF"/>
            <GradientStop Color="#FFFFFFFF" Offset="1"/>
        </LinearGradientBrush>
    </Border.Background>
    <StackPanel>
        <TextBlock x:Name="eventName" Text="Amazing Music" FontSize="24" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Padding="0,0,0,0"/>
        <TextBlock x:Name="eventDescription" Text="Amazin music in that house" TextWrapping="Wrap" FontSize="14" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" MaxWidth="300" />
    </StackPanel>
</Border>
